Annelein Meisner

Researcher | PhD

I am a soil ecologist studying how extreme events can affect soil microbes in terrestrial ecosystems. Soils are an important regulator of many ecosystem services such as clean water, carbon cycling and plant performance. Ecosystems will likely be exposed to extreme fluctuations in precipitation and temperatures due to ongoing climate change that may increase the incidence of fluctuations in drought and rainfall events, as well as increase frequency of freeze-thaw events. As moisture and temperature are important regulators of soil microbial activities, it is important to understand how microbial community structure and functioning respond to fluctuating environmental conditions. Currently, I study how drying-rewetting and freeze-thaw cycles affect soil microbial communities, their functions and activity. In addition, I study the consequences of these changes for carbon cycling and ecosystem functioning.

Coping with extremes: microbial responses to environmental change

Ecosystems worldwide are predicted to be exposed more frequently to extreme fluctuations in precipitation and temperatures. These fluctuations can lead to an altered number of freeze-thaw cycles and more intense drought and rainfall events. This project has as aim to understand how microbial communities, their functions and activity are influenced by fluctuations in water availability and freeze-thaw cycles. In addition, I study how these changes may affect carbon cycling and ecosystem functioning.

Funded by an international career grant from the Swedish Research Council VR (2015-2019)

Microbial growth response upon rewetting dry soil

In this project, I studied the patterns of bacterial and fungal growth upon rewetting air-dried or partially dried soils. For more information on this project, please see the project page.
